Abstract
This invention generally relates to wired and wireless ultra wideband (UWB) data communications apparatus and methods, and in particular to UWB receiver systems and architectures. An ultra wideband (UWB) receiver system comprising: a receiver front end to receive a UWB signal; an analogue-to-digital converter coupled to said receiver front end to digitize said received UBW signal; and a correlator coupled to said analogue-to-digital converter to correlate said digitized UWB signal with a reference signal.
Claims13
An ultra wideband (UWB) receiver system comprising:
- a receiver front end to receive a UWB signal;
- an analogue-to-digital converter coupled to said receiver front end to digitise said received UWB signal;
- a correlator coupled to said analogue-to-digital converter to correlate said digitised UWB signal with a reference signal,
- a reference signal memory to store said reference signal and controller to determine reference signal data from said digitised UWB signal, and to write said determined data into said reference signal memory;
- and wherein said receiver front end includes a received signal level adjuster, and wherein said signal level adjuster is responsive to said reference signal.
